Spatial Impulse Response Rendering (SIRR) is a recent technique for reproduction of room acoustics with a multichannel loudspeaker system. SIRR analyzes the direction of arrival and diffuseness of measured room responses within frequency bands. The direction is estimated using sound intensity, and diffuseness from the ratio of active sound intensity and energy density. Based the analysis data, a multichannel response suitable for reproduction with any chosen surround loudspeaker setup is synthesized. When loaded to a convolving reverberator, the synthesized responses create a very natural perception of space corresponding to the measured room. In this paper, new listening test data, and applications to processing of continuous sound are presented.
